## Maths Symbols Uses with Examples

**+ (Plus)**: Represents addition. Used to combine quantities. Example: 5 + 3 = 8**– (Minus)**: Represents subtraction. Used to find the difference between quantities. Example: 10 – 4 = 6**× (Multiplication)**: Represents multiplication. Used to find the product of numbers. Example: 3 × 7 = 21**÷ (Division)**: Represents division. Used to find the quotient of numbers. Example: 12 ÷ 3 = 4**= (Equal)**: Represents equality. Used to show that two expressions have the same value. Example: 2 + 2 = 4**< (Less than)**: Indicates that one quantity is smaller than another. Example: 5 < 8**> (Greater than)**: Indicates that one quantity is larger than another. Example: 10 > 7**π (Pi)**: Represents the ratio of a circle’s circumference to its diameter. Used in geometry and trigonometry. Example: Circumference = π × Diameter**∑ (Summation)**: Represents the sum of a sequence of numbers. Used in calculus and series. Example: ∑(i=1 to 5) i = 1 + 2 + 3 + 4 + 5 = 15**∆ (Delta)**: Represents a change or difference. Used in calculus and science. Example: Δx represents the change in x.**√ (Square Root)**: Represents the principal square root of a number. Used to find the value that, when multiplied by itself, gives the original number. Example: √25 = 5**% (Percent)**: Represents a proportion out of 100. Used to express percentages. Example: 25% = 25/100 = 0.25**∈ (Belongs to)**: Indicates that an element belongs to a set. Example: x ∈ {1, 2, 3} means x is an element of the set {1, 2, 3}.**∞ (Infinity)**: Represents an unbounded quantity. Used in calculus and limit concepts. Example: lim(x → ∞) 1/x = 0**≠ (Not Equal)**: Indicates that two quantities are not equal. Example: 7 ≠ 10**° (Degree)**: Represents a unit of measurement for angles. Example: A right angle measures 90°.**≈ (Approximately Equal)**: Indicates that two quantities are nearly equal, but not exactly. Example: π ≈ 3.14159**∠ (Angle)**: Represents a geometric angle formed by two rays. Example: ∠ABC represents the angle at vertex B between rays BA and BC.**∴ (Therefore)**: Used to indicate a logical conclusion or implication. Example: If x = 3, and y = 2x + 1, then y = 7. ∴ y is equal to 7.**∵ (Because)**: Used to introduce the reason or cause for a statement. Example: ∵ x = 5 and y = x + 3, therefore y = 8.**∫ (Integral)**: Represents the concept of integration in calculus. Example: ∫ f(x) dx represents the integral of the function f(x) with respect to x.**∇ (Nabla, Gradient)**: Represents the gradient operator in vector calculus. Example: ∇f represents the gradient of the scalar function f.**∂ (Partial Derivative)**: Represents a partial derivative in calculus. Example: ∂f/∂x represents the partial derivative of the function f with respect to x.**∩ (Intersection)**: Represents the intersection of sets. Example: A ∩ B represents the set of elements that are in both sets A and B.**∪ (Union)**: Represents the union of sets. Example: A ∪ B represents the set of elements that are in either set A or set B.**∴ (Logical AND)**: Represents logical conjunction in propositional logic. Example: P ∧ Q is true if both propositions P and Q are true.**∨ (Logical OR)**: Represents logical disjunction in propositional logic. Example: P ∨ Q is true if at least one of the propositions P or Q is true.**~ (Tilde, Negation)**: Represents logical negation or bitwise NOT. Example: ~P is true if proposition P is false.**⇒ (Implies)**: Represents logical implication. Example: If it is raining (P), then the ground is wet (Q). P ⇒ Q.**∀ (For All)**: Represents universal quantification in logic. Example: ∀x, x > 0 means “For all x, x is greater than 0.”
